A/N Sorry about the bried intro, had planned to make it longer, but if it weren't for annoying siblings (shoots pointed glare at unsuspecting brother) then I would have written more, and anyways enjoy! I hope you liked the interaction between Chelsea and Sherlock!

Chelsea sighed as she made her way to the lecture. It was nearly eleven o'clock, and already she felt tired. Hoping that Sherlock would be able to help her, she hurried into the lecture room, and sent a brief smile to everyone around her. A red-haired girl moved over, and glared at her, before glancing at the lecturer.

"What the hell, Chelsea?! Where were you?" She furiously whispered in her friend's ear. Chelsea sighed.

"It's okay Jess, I was just chatting to someone." Jess rolled her eyes.

"And that was so important that you ignored my text for a good five minutes." She replied sarcastically. Chelsea pulled out her phone, and passed it to Jess, who glanced at the picture, and then back up at Chelsea. What the heck is this was clearly written all over here face.

"Someone decorated my bedroom, while I was asleep." The look on Jess's face was priceless when she heard that, and she clapped her hands over her mouth, and stared at Chelsea. They stared at each other for a while, and then Jess leaned forward.

"What are you going to do about it?" She whispered.

"I've already done something about it. I've this bloke onto it."

"Who?"

"He's a bit of an enigma really, he's...

"Sherlock Holmes, Consulting Detective." A deep baritone cut in smoothly, interupting their secret conversation. Jess squeaked, and turned around her eyes widening in surprise. Chelsea waited until her heart rate had calmed back down to it's slightly under average resting rate, before she turned to face Sherlock. His face was only inches from her's, and she stared into his ever-changing eyes for a few seconds, before blinking, and leaning back. She gazed at him calmly and then she noted his change in attire.

"Nice scarf." She complimented, and his eyes narrowed slightly, before he nodded, and studied Jess. Before he could say anything Chelsea cut in.

"If you want to head up to my dorm, and investigate it's number twenty-three A, corridor six, hall 2." Sherlock nodded, and slipped away, leaving the lecture hall as quietly as he had slipped in. Jess turned back to Chelsea.

"Chels, that guy is soooo hot. What the hell?!" Chelsea rolled her eyes.

"Shush, do you mind, I have to listen. We have an exam later this week!" Jess sighed, and nudged her friend twice, before turning and listening to the lecture, although she insisted on nudging Chels again several times during the lecture. When the bell rang signifying lunch, Chelsea slipped out, and sprinted all the way to her room on silent feet, glad to escape her over-inquisitive friend. She paused outside her room, and looked curiously upon a mind-palace involved Sherlock. She coughed once, and then cleared her throat loudly to catch his attention.

Sherlock slipped out of the lecture hall, and following Chelsea's instructions, made his way into her room. It was decorated in obvious admiration to the student. Pictures of her in mid-air were surrounded by roses. Rose petals were scattered across the floor, and Sherlock's mind went into instant deductions. Expensive stationary, Bohemian, left-handed writing, French calligraphy, extensive care to detail, roses exact same hue of white, no blemishes, Rosa Pimpinellifoliae. He prowled restlessly around the room, examining every area affected, and not affected. The stationary was studied intently. Whirling around he closed his eyes, and delved into his mind palace, opening up a room for Chelsea, and storing everything in there he could catalogue. He was just emerging when he dimly heard a cough. Blinking once, he heard someone clear their throat, and he turned to see Chelsea standing by the door, watching him placidly. He blinked again, and she stepped into the room, and gave it a once over.

"Did you get anything?" Her tone was part curiosity part boredom, and he wondered if she met her stalker whether she would be that bored. He nodded, and looked around, before spinning back.

"Do you have anything scheduled for the rest of today?" She blinked several times, and then shook her head looking bored. Sherlock grinned, and almost danced out of the room, leaving Chelsea behind in confusion. Sherlock came back, and raised an eyebrow at her. "You're supposed to follow me." He stated, and she raised an eyebrow at him. Chelsea whirled around and grabbed a tan trenchcoat, and then held out her hand. He sighed, and grabbing her wrist pulled her out of the room, and along the corridor. Chelsea felt the familiar rush of adrenaline coursing through her veins, and her pupils dilated, eyelids narrowing, limbs tensing, muscles working themselves into the precise movements so familiar to her. She sped up, no longer being dragged along Sherlock, but dragging him. She dodged easily through the crowds of people flooding the University halls, and leapt quite easily to the side. The duo pounded down the steps and onto the street, Sherlock slowing automatically to catch a cab, but stopping entirely when Chelsea tugged on his hand.

"Where are we going?" Her face was flushed slightly, and her nostrils flared slowly with each deep breath she took. Sherlock looked at her.

"Baker Street." He stated, his voice clipped, and he went to hail a cab, but Chelsea stopped him.

"Why don't we run there?" Sherlock looked at her like she was mad, and a coy smile rose on her face. "We'd beat the traffic." A smile came out on his face, and he jogged off, letting her pull on her trenchcoat, and follow him. She took off, hands going from thigh to cheek in a sprinters pose, and quickly overtook him. Sherlock sped up to catch up with her, and was impressed slightly when she pulled ahead again. He smiled and pulled up with her, but she pulled away yet again. Speeding up completely she seperated the distance between them by a good five meters, head held high, adrenaline coursing through her like a flood through a break in a dam. Bystanders, and pedestrians turned to stare at them as they thundered by. Chelsea slowed to let Sherlock catch up, and grinned up at him, pleased when he grinned back.

Facing forwards she watched the traffic at an upcoming crossroads, and sprinting forwards took up the challenge. Hands splaying out by her sides, she looked at the cars coming up, and racing out onto the road, placed her hands on the bonnet of a passing car, and flipped over the bonnet to repeat the motions with another. She crossed the road successfully, and pounded along the pavement, smiling widely as she hurdled over various obstacles, jumping and grabbing hold of a signpost to throw herself over a tea table at an outdoor cafe, before executing a perfect landing, and flipping over yet another table. Her parkour, and freerunning skills were into full execution now, and every movement was a performance for those watching, but for her, just a practiced routine which she executed so brilliantly she left passersby absolutely stunned in her wake, and that of the consulting detective following her, hurdling, and throwing himself over objects in a pretty effective, but much less spectacular way than she. Together the pair made quite an attraction as they raced through the streets of London, the Uni student, parkour and free-running extremist in her tan trenchcoat with her hair streaming behind her like her coat, and the Consulting Detective in his blue trenchcoat, curls bouncing ever so slightly with each movement. When they finally arrived back at Baker Street, Sherlock was absolutely breathless, Chelsea only slightly less so. They leaned against the stairs gasping for breath, cheesy grins on their faces, before Sherlock spoke.

"That. Was. Fan-bloody-tastic." He gasped for breath, and chuckled when Chelsea let out a short bark of laughter, followed by a giggle.

"Not so much. I've been preparing for exams, so I've got a bit out of shape. I can run across London at it's widest point, in two hours, and twenty-three minutes exactly. I timed myself. Although that is without hurling myself over random objects." Sherlock grinned at that.

"Yeah. Pretty impressive that." Chelsea nodded at the praise, and smiled.

"Well, just in case you forget I do do parkour, and free-running. Just in case you forget." Sherlock chuckled at the sarcasm in her tone, and then pounded up the stairs followed closely by Chelsea. For the second time that day, she entered the flat, and seated herself. Sherlock turned to her.

"I have a proposition to make." Chelsea looked up at him.

A/N Dun dun dun dunnn! What does Sherlock have to say? Guess. You never will! LOL see ya guys!
